在AppDelegate.h里面添加@property(nonatomic,assign)NSInteger allowRotation;
在AppDelegate.m文件里面添加
- (NSUInteger)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow*)window
{
if(_allowRotation ==1)
{
returnUIInterfaceOrientationMaskLandscapeRight;
}else
{
return(UIInterfaceOrientationMaskPortrait);
}
}
这样默认所以的页面就是竖屏的，在要强制横屏的页面的控制器UIViewController里面，引入#import “AppDelegate.h”
然后
-(void)viewDidLoad
{
[super viewDidLoad];
AppDelegate * appDelegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
appDelegate.allowRotation = 1;
}
就可以让个别页面单独横屏了,在跳出这个横屏页面前修改状态，如下
AppDelegate *delegate= [[UIApplication sharedApplication]delegate];delegate.allowRotation =0;
